Description

Foreliggende oppfinnelse gjelder en fremgangsmåte for samtidig karbonering og kjøling av en væske, hvor karbondioksyd under høyt trykk tillates å ekspandere og oppløses i væsken inntil metning av denne, slik at■overskudd av karbondioksyd som videre føres til kontakt med væsken ikke løses opp i denne, men blir resirkulert og ført inn under væskeoverflaten. Oppfinnelsen gjelder også en anordning for utførelse av denne fremgangsmåte, idet anordningen omfatter en lukket beholder, et væskeinnløp inn i beholderen, minst ett karbondioksydinnløp til beholderen under væskeoverflaten, en utløpskanal for karbonert væske og en resirkuleringskanal som munner ut fra beholderen over væskeoverflaten for føring av karbondioksyd som ikke er blitt oppløst i væsken tilbake til karbondioksyd-innløpet. The present invention relates to a method for simultaneous carbonation and cooling of a liquid, where carbon dioxide under high pressure is allowed to expand and dissolve in the liquid until it is saturated, so that ■excess carbon dioxide which is further brought into contact with the liquid is not dissolved in it, but is recycled and introduced below the liquid surface. The invention also applies to a device for carrying out this method, the device comprising a closed container, a liquid inlet into the container, at least one carbon dioxide inlet to the container below the liquid surface, an outlet channel for carbonated liquid and a recycling channel that opens from the container above the liquid surface for guiding carbon dioxide that has not been dissolved in the liquid back to the carbon dioxide inlet.

En sådan fremgangsmåte og anordning er kjent fra allment tilgjengelig GB-patentsøknad nr. 2 059 791. Such a method and device is known from generally available GB patent application no. 2 059 791.

Videre er det kjent mange forskjellige fremgangsmåter og anordninger, for eksempel fra DE-25 59 651 og DE-29 40 407, for karbonering av væsker, hvor karbondioksyd under relativt lavt trykk og gjennom porøse diffusere føres inn under overflaten av vedkommende væske for deretter under oppløsning i væsken å stige mot væskeoverflaten i form av meget fine bobler. I henhold til DE-29 40 407 blir væsken videre sprøytet i forstøvet form inn i det karbondioksydvolum som ikke er blitt oppløst i væsken og som befinner seg over væskeoverflaten, for derved ytterligere å øke den oppløste karbondioksydmengde i væsken. En pumpe trekker ut karbondioksyd fra nevnte volum av uoppløst karbondioksyd og fører det på nytt inn under overflaten av væsken. Kjøling av væsken oppnås ved hjelp av kjølekretser anordnet i selve væsken eller utenfor væskebeholderen. Furthermore, many different methods and devices are known, for example from DE-25 59 651 and DE-29 40 407, for the carbonation of liquids, where carbon dioxide under relatively low pressure and through porous diffusers is introduced below the surface of the liquid in question and then below solution in the liquid to rise towards the liquid surface in the form of very fine bubbles. According to DE-29 40 407, the liquid is further sprayed in atomized form into the volume of carbon dioxide which has not been dissolved in the liquid and which is located above the liquid surface, thereby further increasing the amount of dissolved carbon dioxide in the liquid. A pump extracts carbon dioxide from said volume of undissolved carbon dioxide and reintroduces it under the surface of the liquid. Cooling of the liquid is achieved by means of cooling circuits arranged in the liquid itself or outside the liquid container.

Disse kjente anordninger for utførelse av disse fremgangsmåter krever således både en karbondioksydkrets og en kjølekrets, og er derfor kostnadskrevende så vel som tungvinte i bruk. US-patent nr. 4 022 119 beskriver en fremgangsmåte og en anordning for samtidig karbonisering og kjøling av en væske ved bruk av ekspanderende karbondioksyd. Karbondioksydet holdes lagret i en tank, hvorfra det føres inn i bunnen av en karboneringsbeholder som er åpen oventil og hvori også den væske som skal karboneres etter hvert blir innført. Den karbonerte væske strømmer over kanten av den åpne karboneringsbeholder og ned i et omgivende kar, fra hvis bunn den karbonerte væske ledes videre for å fylles i beholdere for forbruk. I denne kjente fremgangsmåte, som er tilpasset industriell drift i stor skala, har kjølingen ved hjelp av ekspanderende karbondioksyd som eneste formål å gjøre det mulig å oppløse større mengder karbondioksyd enn det som ellers ville være mulig. These known devices for carrying out these methods thus require both a carbon dioxide circuit and a cooling circuit, and are therefore costly as well as cumbersome to use. US Patent No. 4,022,119 describes a method and a device for simultaneous carbonation and cooling of a liquid using expanding carbon dioxide. The carbon dioxide is kept stored in a tank, from where it is fed into the bottom of a carbonation container which is open at the top and into which the liquid to be carbonated is also gradually introduced. The carbonated liquid flows over the edge of the open carbonating vessel and into a surrounding vessel, from the bottom of which the carbonated liquid is passed on to be filled into containers for consumption. In this known method, which is adapted to industrial operation on a large scale, the cooling by means of expanding carbon dioxide has the sole purpose of making it possible to dissolve larger quantities of carbon dioxide than would otherwise be possible.

Formålet for foreliggende oppfinnelse er da å komme frem til en ny fremgangsmåte og anordning for karbonering og kjøling av væsker, idet nevnte anordning bare arbeider med en eneste krets som er slik utført at anordningen blir enklere og billigere, og gjør anordningen særlig egnet for å frembringe nedkjølte, karboniserte drikkevarer i husholdninger, på kontorer og lignende, hvor det er behov for en raskt og effektivt arbeidende anordning som krever liten plass. The purpose of the present invention is then to come up with a new method and device for carbonation and cooling of liquids, as said device only works with a single circuit which is designed in such a way that the device becomes simpler and cheaper, and makes the device particularly suitable for producing chilled, carbonated beverages in households, in offices and the like, where there is a need for a quickly and efficiently working device that requires little space.

For å oppnå disse formål har da fremgengsmåten i henhold til foreliggende oppfinnelse som særtrekk at overskuddet av karbondioksyd tilføres en kompressor og deretter en kjøler for komprimering og kjøling, før det tilføres væsken. In order to achieve these purposes, the method according to the present invention has as a distinctive feature that the surplus of carbon dioxide is supplied to a compressor and then to a cooler for compression and cooling, before it is supplied to the liquid.

I henhold til oppfinnelsen komprimeres overskuddet av karbondioksyd fortrinnsvis til flytende tilstand. According to the invention, the surplus of carbon dioxide is preferably compressed into a liquid state.

Likeledes har anordningen for utførelse av fremgangsmåten i henhold til oppfinnelsen som særtrekk at en kompressor er anordnet i resirkuleringskanalen og det etter kompressoren er anordnet en kjøler som er tilsluttet karbondioksydinnløpet. Oppfinnelsen vil nå bli nærmere forklart under henvisning til den vedføyde tegning som skjematisk viser en anordning i henhold til oppfinnelsen. Likewise, the device for carrying out the method according to the invention has as a distinctive feature that a compressor is arranged in the recycling channel and that after the compressor a cooler is arranged which is connected to the carbon dioxide inlet. The invention will now be explained in more detail with reference to the attached drawing which schematically shows a device according to the invention.

I en vertikal vegg av en lukket beholder 1 munner det ut en tilførselskanal 2 for væske, slik som vann, mens det i bunnen av beholderen munner ut en høytrykkskanal 3 for innføring av karbondioksyd i væsken, samt en oppfylningskanal 4 for karbondioksyd. Fra bunnen av beholderen strekker det seg også ut en utløpskanal 5 for karbonert væske. Fra den øvre vegg av beholderen strekker det seg en resirkuleringskanal 6 for karbondioksyd. Resirkuleringskretsen 6 er forbundet med en kompressor 7, hvis utgangsside er tilsluttet høytrykkskanalen 3 gjennom en kjøler 8. A supply channel 2 for liquid, such as water, opens into a vertical wall of a closed container 1, while at the bottom of the container there opens a high-pressure channel 3 for introducing carbon dioxide into the liquid, as well as a filling channel 4 for carbon dioxide. An outlet channel 5 for carbonated liquid also extends from the bottom of the container. A recycling channel 6 for carbon dioxide extends from the upper wall of the container. The recirculation circuit 6 is connected to a compressor 7, the output side of which is connected to the high-pressure channel 3 through a cooler 8.

Ved fylling av væske gjennom kanalen 2 oppnås et væskevolum 9 i beholderen 1, og ved innføring av karbondioksyd gjennom fylningskanalen 4 oppnås et volum 10 av karbondioksyd som ikke er blitt oppløst i væsken og befinner seg over væskeoverflaten. When filling liquid through the channel 2, a liquid volume 9 is obtained in the container 1, and when introducing carbon dioxide through the filling channel 4, a volume 10 of carbon dioxide is obtained which has not been dissolved in the liquid and is located above the liquid surface.

På kjent måte blir det uoppløste karbondioksyd som befinner seg i volumet 10 resirkulert gjennom resirkulasjonskanalen 6 tilbake til beholderen 1, eventuelt gjennom en fuktighets-regulator 11. I henhold til foreliggende oppfinnelse finner imidlertid dette sted gjennom kompressoren 7, som bør være i stand til å frembringe en betraktelig trykkøkning i karbondioksydet fra et trykk på omkring 0,7—1 MPa, fortrinnsvis opptil et trykk på omkring 6,5 MPa eller mer, således at karbondioksydet overføres til væskefase. Ved sammentrykning vil temperaturen av karbondioksydet stige betraktelig (opptil omkring 250°C) . Det er derfor hensiktsmessig å dele opp kompresjonen i to trinn ved hjelp av en to-trinns kompressor med mellomliggende nedkjøling. I alle tilfeller kjøles karbondioksydet, som vil være varmt etter sammentrykningen, ned i kjøleren 8, hvoretter karbondioksydet, fortrinnsvis i væskeform, tilføres gjennom kanalen 6 og et innsnevrings-munnstykke til væskevolumet 9, og tillates der å ekspandere og overføres til dampfase. In a known manner, the undissolved carbon dioxide that is in the volume 10 is recycled through the recirculation channel 6 back to the container 1, possibly through a humidity regulator 11. According to the present invention, however, this takes place through the compressor 7, which should be able to produce a considerable pressure increase in the carbon dioxide from a pressure of about 0.7-1 MPa, preferably up to a pressure of about 6.5 MPa or more, so that the carbon dioxide is transferred to liquid phase. During compression, the temperature of the carbon dioxide will rise considerably (up to around 250°C). It is therefore appropriate to divide the compression into two stages using a two-stage compressor with intermediate cooling. In all cases, the carbon dioxide, which will be hot after the compression, is cooled down in the cooler 8, after which the carbon dioxide, preferably in liquid form, is supplied through the channel 6 and a narrowing nozzle to the liquid volume 9, and is allowed there to expand and is transferred to the vapor phase.

Den temperatursenkning som skriver seg fra ekspansjonen i innsnevringsmunnstykket 12 utnyttes for kjøling av væsken samtidig som karbondioksydet i gassform på sin vei mot væskeoverflaten delvis oppløses i væsken og karbonerer denne. The temperature drop resulting from the expansion in the narrowing nozzle 12 is utilized for cooling the liquid at the same time that the carbon dioxide in gaseous form on its way to the liquid surface partially dissolves in the liquid and carbonates it.

I anordningen inngår også utstyr (ikke vist i figuren) for å oppnå påfyll av væske gjennom kanalen 2, som fortrinnsvis munner ut over væskeoverflaten, såvel som utstyr (ikke vist) for påfyll av karbondioksyd i anordningen gjennom kanalen 4 etter behov. The device also includes equipment (not shown in the figure) for filling up liquid through the channel 2, which preferably opens above the liquid surface, as well as equipment (not shown) for filling the device with carbon dioxide through the channel 4 as needed.

En anordning i henhold til foreliggende oppfinnelse og anvendt for karbonering og kjøling av drikkevarer, nemlig som en mineralvannmaskin eller "brusautomat", gir betraktelige fordeler sammenlignet med tilsvarende anordninger med inn-byrdes adskilt karbonerings- og kjølekrets. Forsøk er blitt gjort ved utnyttelse av den angitte fremgangsmåte og ved utnyttelse av en forsøksanordning med bruk av flytende karbondioksyd fra en flaske. Karbondioksydet hadde da en temperatur på omkring +20°C og ble ført inn i et vannvolum på 3 1 og som også hadde en temperatur på omkring +20°C. Ved en karbondioksydstrømning på omkring 100 g/min ble det oppnådd en temperatursenkning i vannvolumet på 6,3°C/lmin, hvilket tilsvarer en kjølingsvirkning på -0,53°C pr. 20 cl og sekund. Dette innebærer i sin tur at anordningen teoretisk vil være i stand til å kjøle ned et normalt drikkeglass (20 cl) av en drikkevare ved +15°C til +5°C på mindre enn 2 0 sekunder. Da vanlig ledningsvann normalt har en temperatur på omkring +10°C, kan man beregne at en nedkjøling av 20 cl av sådant vann til +5°C kan oppnås på mindre enn 10 sekunder. På lignende måte finner karbonering sted innenfor noen få sekunder. A device according to the present invention and used for carbonation and cooling of beverages, namely as a mineral water machine or "soda machine", offers considerable advantages compared to similar devices with mutually separate carbonation and cooling circuits. Experiments have been carried out using the specified method and using an experimental device using liquid carbon dioxide from a bottle. The carbon dioxide then had a temperature of around +20°C and was introduced into a water volume of 3 1 which also had a temperature of around +20°C. At a carbon dioxide flow of around 100 g/min, a temperature drop in the water volume of 6.3°C/lmin was achieved, which corresponds to a cooling effect of -0.53°C per 20 cl and second. This in turn means that the device will theoretically be able to cool down a normal drinking glass (20 cl) of a beverage at +15°C to +5°C in less than 20 seconds. As ordinary tap water normally has a temperature of around +10°C, it can be calculated that a cooling of 20 cl of such water to +5°C can be achieved in less than 10 seconds. Similarly, carbonation takes place within a few seconds.
